Outline

Objective

High resolution biometry of the anterior segment is necessary for the evaluation of new lens generations based on the optical shift principle. The clinical device IOL master focus provide a non-contact biometry of the anterior segment using partial coherence interferometry. The aim of this study was to investigate the axial shift of the different IOL designs during an accommodative stimulus. These results were compared with anterior segment measurements using slit-lamp pachymetry (JÃ¤ger).

Conclusions

Using IOL master focus and pharmacological induced accommodation the changes in anterior chamber depth are smaller than the determined values with slit-lamp pachymetry (Jaeger). The Jaeger values are in correlation with the determined accommodation amplitudes.
